Summary: The Mio DigiWalker C720 is designed for users who desire a car navigation system with an integrated 2 megapixel camera and cutting-edge functionality. Enabling geotagging, stamp the exact coordinates of where a photo was taken and share it with friends and family. The C720 is also equipped with Card Scanner, which inputs business card information automatically, doing away with manual inputting of long addresses and titles.
Summary: I like very mach the form of the unit and the systsm of the cradle. the camera that in the unit is very unique and have several advantages. This gps the mio c720 in my opinion grabs the fastest satellite signal.
Summary: This was a upgrade from the c320 for me, I like the quick response to POI searches and the Camera feature is cool. The MioMap GPS interface is a little advanced for most users but once you learn it you find what the others lack. There are software mods available for this model that enhance the user interface. I got a great eBay deal on mine used.
